Meyer–Schuster rearrangement of 3°-propargyl alcohol to the corresponding α,β-unsaturated carbonyl compounds under SOCl2 catalysis has been reported. Terminal and internal propargyl alcohols efficiently participated in the reaction. Furthermore, we have demonstrated the synthetic utility of conjugated carbonyl compounds to access densely arene-substituted pyrazolines bearing quaternary centers by reacting
据报道,在 SOCl 2催化下,3°-炔丙醇通过 Meyer-Schuster 重排生成相应的 α,β-不饱和羰基化合物。端炔醇和内炔醇有效地参与了反应。此外,我们还证明了共轭羰基化合物通过与盐酸芳基肼反应获得带有季中心的密集芳烃取代的吡唑啉的合成效用。进行同位素标记研究是为了深入了解反应机制。
